  • Build your garden pond: a 1.5m × 5m nominal sheet of flexible 200gsm PE for the water-holding layer.

  • Black face with grey reverse: UV-resistant PE for outdoor ponds and garden water features.
  • Underlay included: 1 separate 3m × 3m sheet of 50gsm fabric for laying beneath the liner.
  • One liner supplied: cut-size tolerance ±5%. Allow for depth and edging; prepare smooth ground and remove sharp debris before fitting.

Description

PE pond liner and underlay in one bundle

A nominal 1.5m × 5m black and grey 200gsm polyethylene liner, supplied with 50gsm fabric underlay for the layer beneath. The flexible sheet provides a nominal 7.5m² of flat liner material.

One liner with fabric underlay included.

Check the material and both contour measurements before ordering. This is a PE bundle rather than an EPDM rubber liner.

Make sure the narrow side reaches far enough

The 1.5m dimension has to reach down into the pond, across the base and over the edges. It is not a measurement of the water surface width. Shelves and changes in level also use some of the sheet.

Measure the longest and widest routes along the actual contours and add the material for your perimeter finish. Compare both with the 1.5m × 5m liner and account for its ±5% cut-size tolerance. Flat area alone cannot confirm the fit.

Prepare the pond for both layers

The flexible PE is UV-resistant for outdoor pond use. Place the included fabric beneath it after clearing and smoothing the supporting surfaces.

Remove sharp objects

Clear stones, roots and debris from the base, sides and shelves. Underlay does not replace this preparation.

Arrange the fabric

Plan the coverage and any overlaps before positioning the liner. Assess whether the actual ground conditions need additional protection.

Fit the liner gently

Ease it into the contours without stretching it tight across gaps. Keep enough material for the edges and check before filling.

Know what the two GSM figures describe

The bundle supplies one nominal 1.5m × 5m 200gsm PE liner and 50gsm fabric underlay. The black-faced liner has a grey reverse; the fabric forms a distinct protective layer beneath it.

GSM means grams per square metre and applies separately to each material. The figures are not thickness measurements or a combined liner rating. Pond edging, plants, stones and other installation accessories are not included.

Questions before fitting

Is the fabric underlay included?

Yes. This is the liner-and-underlay bundle, with 50gsm fabric included. Plan its arrangement and coverage for your excavation before fitting the liner.

Will the liner fit a 1.5m by 5m water surface?

No. Those are the nominal flat sheet dimensions. Some of each dimension is needed for depth, sides and the perimeter finish. Measure through the actual pond shape to choose a size.

Does the fabric guarantee protection on any ground?

No. Remove sharp objects and prepare the supporting surfaces. The 50gsm fabric is a lightweight layer, so assess any further protection your ground conditions need.
